Crank pin hole question

[Tkul88]

Hi quick question.

If the timing is out on a car, how do I make sure the crank pin is in the right slot in the flywheel? (yes I know usually if it's out the valves are fucked etc etc.)

Guide States to go by the horizontal cam slots. But if the timing is out, how can I be sure it's not going in a balance hole at horizontal?

Thanks

Which the spark plug out on cyl 2 or 3 and put something carefully onto the top of the piston to show TDC when it's at TDC the pin will only go into the correct hole

also timing mark on the flywheel.

Thanks

Mark on flywheel is best.

And the mark on the crank pulley? Thats what i used as my flywheel is off.

Thanks guys

Thats floating, and theres nothing to line it up to. Flywheel you get it bang on and it slots in.

Sorry i meant the crankshaft groove not the pulley.

Right can't use flywheel method as engine in still in the car.

If I get cylinder 3 (assuming right to left is 1-4) to TDC the crank pin will not locate until after TDC and traveling back down.

Theres a hole in the gearbox bell housing. Its under PAS/coolant pipe. Line up the slot in flywheel to the 0 mark on the flywheel.

It should be one and four at TDC.

Ahh I see. Thanks!

 

[Tkul88]

Can I just double check. The only visible mark that was on the flywheel was a bit of green paint? Is that what I was looking for? Or is it a physical slot as you say?

 

[bloke]

bit of a groove, might of had some paint thrown in it though as it can be a bit fiddly to see.

get crank to tdc with big screw driver down no.4, then check for locking hole in crank, be careful though as it is easy to miss it and get the balance drilling but the pin won't go all the way in. also make sure you have the proper pin am 99% certain if you have a k4m pin it will screw all the way in in the balance drilling.

meant to say 'check timing mark on flywheel' and then lock the crank.

 

[Tkul88]

Was going to post this to ask if this green mark was the TDC mark. Then I noticed the notch in the flywheel next to the green bit!

Cylinder 4 also at TDC - checked using screw driver method.

For anyone that needs some help that's come across this post, see image!

P.s yours may not have green paint, but should have the mark, as everyone mentioned above.

 

[bloke]

be very careful as where the mark is now you're not at tdc, when you insert the pin make sure the crank won't move either way. it will need to move a 'touch' to get the pin in place.

 

[Tkul88]

Do you mean get that notch between the two lines of '0'?

If I rotate the engine any more, it won't be at TDC. I'm 99% it's at max travel.

Crank won't budge either way. I'll triple check tomorrow, worst case I'll just have to crank it back to this position.

Thanks for the help anyhow.

could just be the angle of the pic, tdc hole will be snug fit.

 

[AlexW]

Yeah looks like angle of pic tbh.
Balance hole is further away, by a lot I believe.
